Black line along the right side near the center when copying ONLY

Not sure, but one possibility is that your paper you are copying is not all the way to the edge of the copier. If there is a crack along the edge where light from the room can get in it will show up black in those areas. You will see the same effect if you leave the top of the copier off and try to copy something. There could also be something wrong with the scanner arm preventing it from moving all the way to the edge of the window.

If it is along the edge of the print, it may be the edge of the book page you are seeing. if it is going through the text of the page, your scan carriage is likely skipping. If you don't see this on copies of single sheets of paper laid on the glass, then the weight of the book may be deforming the glass enough to catch the scan carriage as it passes. If you see it on single copied sheets, there is probably something on one of the scan rails under the glass that the carriage is "hopping" over as it passes. You could try watching the scan carriage move while holding the lid open to see if the carriage "hops" once during a scan.

Your ADF is not feeding the paper straight. The black line is the gap created when the edge of the gap
has a gap along the edge.

* Adjust your feed bars so that it holds the paper tightly centered to the ADF.
* Check that there is not dust in the feed path of the ADF roller and it is clean.

You need to adjust the position center of the scan materials.. The scanner pulls sheets fronm the center of the feeder. Using a single sample page to scan.. You need to move the feed guides the same distance as your black line - either to left or right as appropiate.. (Which side is the mark?) to find the center w/out leaving black line edges. Keep adjusting it till you eliminate the black line. Foxed me good first time I saw it..

If you have the black line on copies and scans but printing from P.C is fine, then your scanner is broken.

Contact your printer manufacturer for a replacement or repair.

Lift the lid and to the left of the main glass is a smaller glass; that is what scans during the feeding process. Make sure that it is completely clean; even a speck of dust can cause a line to appear. I took a lens wipe and cleaned mine and my line was gone.

I had this same problem but after while it went away - so my solution would be to just keep using it, and perhaps it will solve itself.

I was getting a verticle black line and I had to clean the glass, the long white bar above the glass, and the white and black rollers before my problem was solved.
